Yes, if AF in driver set globally, Unreal starts using AF over mipmapping, I clearly see it. Distant textures look even slightly smoother in comparison to Direct3D mode which has barely noticeable shimmering on them. nGlide now shows no shimmering at all, all looks as it should be, nothing to complain.

I get very bad texture aliasing (shimmering) when mipmapping is disabled.Forcing AF on the global profile enables mipmapping in nGlide, but doing so can cause issues with other applications/games.Using AF on the game profile doesn't work. I get AF but no mipmapping.

Please pay attention to the arch in the upper-right and the floor below it. View at 1080p60.

First thing I will try is the automatic approach: forcing AF internally in nGlide for every Glide game that use mip-mapping (with enabled MM itself of course).

If this won't bring any new problems, then we're good - no need for new option. You will no longer have to mess with GPU control panel and it won't affect games that don't use mip-mapping (AF cannot be used with Glide titles utilizing texture atlases).

With MM+AF we will have the best of both worlds - no shimmering and sharp textures.

If it will introduce some glitches, then I'll probably won't have any other choice but to make it configurable.
